Ajax向服务器发送GET请求。服务器返回成功结果。
Server response:
[{"result":"success"}]
但是ajax没有显示任何responseText。 Firebug显示红色的get请求。
Ajax代码部分:
var params = "&id=" +id + "&phone="+phone + "&account_active=" + activeAccount + "&fname="+fname + "&lname="+lname + "&time_zone="+timezone + "&street="+street+"&suite="+suite+"&ring="+ring+"&city="+city+"&state="+state +"&zip="+zip+"&call_time="+callTime +"&call_length="+callLength+"&call_count="+callCount;
var xmlhttp = getXMLObject();
xmlhttp.open("GET",'agent_manager_response.php?cmd=fsave'+params,true);
xmlhttp.onreadystatechange=function(){
if(xmlhttp.readyState==4 && xmlhttp.status==200){
var data = eval(xmlhttp.responseText);
if(data[0].result == "success"){
alert('Successfully saved');
}
else{
alert("Error saving data\nError: " + data[0].result);
}
}
}
xmlhttp.send(null);
服务器代码:
$result = mysql_query($query,$con);
$data=array();
if(!$result)
array_push($data,array('result'=>mysql_error()));
else
array_push($data,array('result'=>'success'));
echo json_encode($data);
Ajax响应DOM选项卡(来自firebug)

这就是我在网络标签中的全部内容:
答案 0 :(得分:0)
添加内容类型:
xmlhttp.setRequestHeader('Content-Type','application/json');
并改变:
var data = eval(xmlhttp.responseText);
到
var data = eval( '(' + xmlhttp.responseText + ')' );
